So Over It Contest #6: Civil War Edition

No winners for the last contest. (The answer was the Sputnik Monument. A second acceptable answer would have been The Hotel Cosmos. Both are located in the Russian capitol, Moscow.)

Now, on to the new. There is a hint for this one. 150 years ago this week, something happened at this place that would change the career of one of the U.S. Civil War’s most famous figures. Once again, the first person to correctly identify the location below and its significance in comments wins a free ebook copy of Dismantle the Sun. (You can leave comments here, on Facebook, or on Twitter. All are equally acceptable.)
